Overheating
These are my symptoms:
o When at normal driving speed no issues at all - temp gauge registers at about 190 degrees
o Serious Wash DC stop and go beltway traffic immediately causes the temp gauge to go towards 240 - as soon as I start moving it returns to 190
o When I turn on the HVAC regardless if I'm moving or not, it immediately heads towards 240 again - turn it off and it returns to 190
o No codes at all
o Changed anti-freeze, 180 themostat about five years old, visual inspection of radiator (top and bottom) is free of debris, hoses are pliable, fans are kicking on
Where do I go from here?
Thanks

Go ahead and wash the outside of the radiator and condenser anyway. Mine looked clean, but after washing and blowing out with air, it dropped my temperatures 30-40 degs. I was ready to buy a new radiator and fans.

Verify if your fans are running when the HVAC is turned on. If not, look at the ground pack at the right forward frame rail immediately adjacent to the hood riser. If they are working, you'll probably need to wash out or blow out the debris in the vanes of the condensor by either fabricating or buying some sort of water/air wand, between the radiator and condensor.

1. You could get a 160 degree thermostat. Have you tested your current thermostat to make sure that it is opening, put it in a class of hot water to check.
2. Set your cooling fans to come on earlier.

I'm in AZ. I don't even watch my coolant temperatures anymore. The DIC is set to the oil temperature only. Mine has reached 254 degrees climbing from 5,200 ft to over 7,000 ft altitudes, in heavy traffic on two lane winding mountain roads. As soon as I'm able to get into a higher gear and away from traffic, it drops down to normal. It doesn't concern me as long as it fluctuates normally.

And apparently the immediate previous poster MISSED point #5 that the original poster said his fans were kicking on when the immediate previous poster suggested to check fuses and relays...
In hind sight, I was only replying to the symptoms prior to the a/c being turned on.
Let's come up with more ideas for him...
How about incorrect belt tension or a/c clutch causing drag?
